Answer:
10° and 80°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other angle is 7x + 10 , so
x + 7x + 10 = 90
8x + 10 = 90 ( subtract 10 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
and 7x + 10 = 7(10) + 10 = 70 + 10 = 80
Thus the 2 angles are 10° and 80°

which is just -0.6
Answer: 5 cookies and 6 brownies.
Step-by-step explanation: If she decides to buy 5 cookies it will cost her $2.50. This means she can still spend $12.50. If we need to find how many brownies she can buy, the expression 12.50/2.25 can explain. In this case, she can buy 5 brownies and will have $1.25 left over
